To all whom t may concern lle 1t known that l, CHARLES YV. HART, a

-citizen of the United States, residing at Charles City, county 'ofFloyd, and State of lona, have invented new and useful lmprcveinents in.Carburcters, of which the toly lowing is a speciiication.

My invention relates to improvements in ca rbureters.

rlhe object ofi'iny invention is to provide l'iydrogen to combine Vwiththe carbon.

ln the following description, reference is had to 'the accompanyingdra-wings, in which-- f Figure l carburetor, partially broken away onthe line fue Fig. 3 to .show the by passes. Fig. is a sectional view,drawn on line y of Fini. l, showing one of the iioat rs with its valvesand the by pass pertaining thereto. Fig. 3 is a sectional View, drawn online i12-Y of Fig. l.

Lilie parts are 'identified by the same reference characters 'throughoutthe several viewsa Briefly stated, the siniplest and l believe, the bestmeans for carrying out niy newly invented method consists in subdividingthe is plan vieu7 of my improved air in a carburetor, and directing oneof the.

currents into the pathof a supply of liquid hydro-carbon to vaporizeandl atomize the latter, in the desired quantity, another cui'i rentbeing at the saine time directed into the path. oi a supply of waterto-likevvise vaporize or atoniize the required quantity, and thenre-uniting mixing the tvvo currents, preparatory to the ignition of themixture inr the cylinder o 'i an internal conibustion engine, eitherwith or witl'ieut an additional supply oli-fresh air'ivhich will beadmitted to excessively charged niixturei'i. By subdividing the aircurrents and mixing each directly with one of the liquids, the

i relative proportions of each liouidjto the air can be inaintaincdinsuch a ratio that the quality of the mixture delivered tothe engine maybe kept substantially at the right proportions by the admission ofireshvair through a spring` actuated regulating valve, whenever thev suctionbecomes `so great kas to have a tendency to overcharge the vapor withthe liquids or liquid products. y

lleiierringto the drauf'ings, a valvecasing l is provided with a passage2, controlled and, normally closed by a spring actuatedy valve 3. .iiris admitted 'to the inlet cavity Ll througlra duct 5 and the valve 3being closed, a portion of thc` air passes to the outlet cavity G,through a by pass?, haing a.

the admispreferably by 'a Another portion olf the air port S for liquidhydrocarbon, sion of which is controlled needle valve tl.

is delivered from the inlet cavity through aby pass l0, which isprovided with a similar water inlet port, controlled, preferably byneedle valve l2, rlhe ltwo currents are united and mixed 'in the outletcavity 6 and dclii'cred to the engine cylinder through duct lilheneverthe suction is excessive, the 'valve opens against the tension of springil and delivers an additional quantity of iii-eeh air directly 'from theinlet to the out let cavity, thus diluting the charge, Which wouldotherwise contain of liquid in such cases, and also relieving thesuction in the by passes.

For light loads, no Water is required, and the arrangement is thereforesuch that it requires a greater degree of suction to draw the water,than to draw the oil'. Thegreater specilic z(gravity ot' the Water alonetends to prevent its delivery when the suction is light, but it willordinarily be found advisable t0 alsoniaintain the water supply at ason1ewhat lowerlevel than that of the oil. "Water and oil cavities G and17 respectively are preferably provided, and the feed through their.inlet ducts 18' and 19 controlled'by i valves 2l operated by floatsil tomaintain il a constant level, with suction ducts 23 leading tothe ports8 and ll troni the oil and Water cavities respectively. The valves and.floats in the oil cavity are the saine as those -in 'the lWater cavity,the only di"`rference bean excessive supply- .iii

5 troduce Water vaporor steam in to a carbureter for the purpose offacilitating comibustion, but I have found that by introducing it inliquid form and causing its evaporation Within the cylinder, considerable additional pressure will be developed, and at a lower temperature,since the Water Will absorb a large number of heat units which becomelatent with vaporization. The quantity of Water introduced can also beregulated to suit the requirements of all the varying conditions met inpractice, and it is highly essential that means be provided which Willadequately maintain the correct proportions of the introduced lwater tothe supply of hydro-carbon and air which make up the balance of thecharge. By dividing the incoming air and separately charging one portionwith Water and another portion with hydro-carbon, I am enabled to avoidl any interference by the vapor absorbed from one of the liquids withthe absorption ofl vapor by the air from the other liquid, and I,therefore, believe that I am the iirst to provide for the intrc ductionofiwater and of hydro-carbon vapor into the air in proper quantity andin the proportions required for thc variable charges of explosivemixturer delivered to internal combustion engines, since I have notfound it practical to introduce both vwater and hydro-carbon into thesame body of air and secure the proper proportions of both by so doing.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A carbureter provided with a mixing chamber, an air inlet, threepassages between said inlet and mixing chamber, means for admittingliquid fuel to one of said passages, means for admitting Water toanother of said passages, and means for resilienty controllingfthepassage of a diluting charge-5f air through the third and centralpassage.

In testimony whereof I allix my signuture in the presence of twowitnesses.
